  "textContent": "The present application discloses an electromagnetic shield device, a wireless charging transmitting terminal, a wireless charging receiving terminal and a system. By providing an electromagnetic shielding device between a power transmitting coil and a power receiving coil and making a magnetic sheet comprised in the electromagnetic shielding device not cover the power receiving coil, the magnetic field acting on the metal material is reduced on one hand and the coupling coefficient between the power transmitting coil and the power receiving coil is increased on the other hand, which reduces the intensity of the emitted magnetic field without changing the required voltage. This reduces an amount of heat and loss during wireless charging and improves charging efficiency.",
